Need a bit of info to help make the right battery charger choice? Need some FAQs for reference? Not a problem, have a look below.
Which charger goes with which battery?
This can be worked out using a simple formula: The battery’s Ah number divided by 10 gives the charger’s ampere rating; this device charges a battery within 12 hours (overnight), when the battery is 50% discharged.
Can a maintenance-free battery be charged, as well?
Yes, this is possible. However, charging needs to be monitored.
CAUTION: Never charge a battery over 14.6V, since batteries form gases and cannot be refilled with distilled water. Do not charge for more than 8 hours.
Does the battery have to be disconnected, in order to be charged?
For safety reasons, we recommend this for all devices! If charging goes unsupervised, the vehicle voltage can reach such a high value that the on-board electronics becomes damaged! Prior to charging the battery, the potentially available battery plug has to be removed. When charging, the battery can accumulate gas and if leaking acid splatters it can corrode or cauterize the engine’s plastic parts.
Can a GEL battery be charged, as well?
Yes, but only using charging devices specially designed for gel batteries. A charging device for gel batteries should not exceed the end voltage of 14.2 Volts.
How can I keep my battery in hibernation?
Batteries may remain continually connected only to charging devices with an electronic charge maintenance function. Conventional charging devices cannot and must not remain continually connected, since a residual current continually flows, thereby leading to overcharging (gassing) of the battery.
